Ok, so the old theme was an eyesore. Ugly. Pretty bad all around. But it's gone now, so hit F5 twice and enjoy the new looks!
On to the real news now: a bug-tracker has (finally) been added to opentk. Please use the "Create Content" -> "issue report" link to report bugs or request features (existing content will be migrated from the forum to the bug tracker).
There is a little polishing left to do during the next few days (navigation, performance) and I'd love to hear suggestions and opinions. I'd also appreciate it if you can test the site on Konqueror, Safari, IE6 or Firefox 2, as I don't have access to these. Thanks!
